CHEMISTRY GLOSSARY
oligosaccharide → oligosaharid
Oligosaccharides are carbohydrates containing from three to ten monosaccharide units, each joined to the next by a glycoside bond.
organometallic compound → organometalni spoj
Organometallic compounds are compounds in which there is a covalent connection between atoms of carbons and atoms of metal (C-Me).
oxonium ion → oksonijev ion
Oxonuim ion (H3O+) is formed when a molecule of water binds with a proton.
Pauling scale → Paulingova skala
Pauling scale is a numerical scale of electronegativities based on bond-energy calculations for different elements joined by covalent bonds. Electronegativity is the power of an atom when in a molecule to attract eletrons to itself. Fluorine is the most electronegative element with a Pauling electronegativity value of 4.
electrolytes → elektroliti
Electrolytes are substances which, when melted or dissolved in water, conduct electric current. By melting or dissolving they are dissociated into electrically charged particles (ions) which are able to conduct electric current. By passing of electric current the transfer of matter occurs. Positively charged particles (cations) travel towards the negative pole (the cathode) and negatively charged particles (the anions) travel towards the positive pole (the anode). Liquid metals, in which the conduction is by free electrons, are not usually regarded as electrolytes. Solid conductors of ions, as in the sodium-sulphur cell, are also known as electrolytes. Depending upon how it conducts electric current, matter can be divided into strong electrolytes, weak electrolytes and nonconductors.
enzyme → enzim
Enzyme is a protein that acts as a catalyst in biochemical reactions. Each enzyme is specific to a particular reaction or a group of similar reactions. Many require the association of certain nonprotein cofactors in order to function. The molecule undergoing a reaction (the substrate) binds to a specific active site on the enzyme molecule to form a short-lived intermediate: this greatly increases (by a factor of up to 1020) the rate at which the reaction proceeds to form the product.
epoxy resin → epoksi smola
Epoxy resins are thermosetting resins produced by copolymerising epoxide compounds with phenols (e.g. epichlorohydrin and bisphenol A). They contain ether linkages (-O-) and form a tight, cross-linked polymer network. Toughness, good adhesion, corrosive-chemical resistance, and good dielectric properties characterise epoxy resins. Most epoxy resins are two-part types which harden when blended.
polar solvent → polarno otapalo
Polar solvent is a liquid with polar molecules which dissolves polar compounds, because the charges on the endings of the solvent’s molecules attract the elements from ion crystals.
